  • A ball is whirled in a horizontal circle of radius straight side of a track. How much centripetal force is required to keep that racecar on the track if the radius of the curved end of the track is 125 m.r, speed v and acceleration a.

  • The velocity is increased to 2v. The acceleration of the ball is:
